[QUOTE="2Wheels, post: 209642, member: 3804"] make sure the bike is sufficiently warmed while doing your test runs, cold two strokes run like shit. once you get it warmed up, if it still is going flat on overev lay it on its side for a bit while running to make sure the bowl is full up, than take another pass. If it screams on top but then goes back to usual, you have found your problem. Try it once or twice for good measure. [/QUOTE]
